Duke doesn't return a double-digit scorer from last year's team, so the opportunity to practice in August and play four games outside the country came along at a good time.

The Blue Devils swept three games from the Chinese Olympic team, then beat the United Arab Emirates national team on Aug. 25 before returning home.

-- 6-5 freshman Austin Rivers, probably a one-and-done point guard, will be in charge of distributing to the shooters while also manufacturing his own points.

Rivers averaged 14.3 points, 2.3 assists and 3.8 turnovers in the four games. He was 5-of-21 on 3-point tries.

-- Coach Mike Krzyzewski is emphasizing scoring in the post this offseason, and 6-11 senior power forward Ryan Kelly is the focal point. Kelly's 3-point range fits well with the Blue Devils' 4-out, 1-in offense, but he's also showing he can score in other ways. Kelly averaged a team-high 15.0 points and 8.3

rebounds. He shot 67.7 percent from the field (23-of-34).

-- Guards Andre Dawkins and Seth Curry will do most of the 3-point shooting. Dawkins averaged 14.3 points overseas and was 14-of-29 from 3-point range (48.3 percent). Curry averaged 13.5 points and made 11 of 30 3-point tries (36.7 percent).

-- Duke has three Plumlee brothers on the roster. Senior Miles Plumlee (6-11, 245) averaged 8.3 points and a team-high 9.8 rebounds on the trip, junior
